I believe volumes 1 through 6 were edited by Ralph Read, volume 7 by Harry Lorayne. All 8 volumes are great references to have and constitute a compact "working library" of conjuring techniques, routines and advice. Everyone serious about magic should own a set! Sold as sets, they are often discounted, and copies show up on eBay frequently. Even new, the prices range from just $20 to $30 per volume, which is really a bargain for large hardbacks with such practical information.

Thank you very much for answering my questions about the Tarbell Volumes. That is really great to know! I'm going to have to order my set of them right away thanks to your insight. :) Especially at such a great price. Thank you for helping me again. I really appreciate it. ;)
